NIV adjudications for student and exchange visitor visas decreased by about 2 percent from fiscal years 2012 through 2017 (1.01 million to 993,000) overall, but experienced a peak in fiscal year 2015 of 1.2 million.

State officials partly attributed the overall changes in student and exchange visitor visa adjudications to the extension of the validity period of such visas for Chinese nationals, which represented the largest single country of nationality for student and exchange visitor visas in fiscal year 2017 (19 percent). In November 2014, the United States extended the validity period of the F visa for academic students from 1 year to 5 years. State officials noted that similar to tourist and business visitor visas, there was an initial surge in Chinese F-visa applicants due to the new 5-year F-visa validity period that began in fiscal year 2015, but the number dropped subsequently because Chinese students with such 5-year visas no longer needed to apply as frequently for F visas. State data for this time period indicate that the number of visa adjudications for F visas for Chinese nationals increased from about 267,000 in fiscal year 2014 to 301,000 in fiscal year 2015, followed by a decline of 172,000 in fiscal year 2016 and 134,000 in fiscal year 2017.
